Respiratory and cardiac motion leads to image degradation in Positron Emission Tomography (PET)
which impairs quantification. In this book  the authors present approaches to motion estimation
and motion correction in thoracic PET. The approaches for motion estimation are based on dual
gating and mass-preserving image registration (VAMPIRE) and mass-preserving optical flow
(MPOF). With mass-preservation  image intensity modulations caused by highly non-rigid cardiac
motion are accounted for. Within the image registration framework different data terms 
different variants of regularization and parametric and non-parametric motion models are
examined. Within the optical flow framework  different data terms and further non-quadratic
penalization are also discussed. The approaches for motion correction particularly focus on
pipelines in dual gated PET. A quantitative evaluation of the proposed approaches is performed
on software phantom data with accompanied ground-truth motion information. Further  clinical
applicability is shown on patient data. The book concludes with an outlook of recent
developments and potential future advances in the field of PET motion correction.
